What to know about your three in one unit.

An important thing to know about the three in one machines is that these units are very sensitive and must be cleaned each month in order to do their job. It is crucial to know how to do this properly and to remember to maintain them on a monthly basis.

Ensure the unit is operating properly:

• To make sure the unit runs smoothly, dust must be cleared from the sensors
• The easiest way to do this is to use a vacuum with a soft bristle head, and gently clean around the edges of the unit
• In the event that one of the units begins to chirp, refer to your owners manual

When to reset the unit…
